Synthesis of new erodable polymers response to environmental stimuli; Atarashii kankyo chowagata bunkaisei plastic no kaihatsu

Abstract

This report relates to the designing of functional materials that decompose in response to various signals. A derivative of {alpha}-bromomethylstyrene is caused to act on the living anions of {alpha}-methylstyrene for the synthesis of a pyrolytic polymer having unsaturated groups at its terminals. The terminal double combinations of this polymer split under the influence of heat, acid, or base for depolymerization which is quantative, and the decomposition temperature may be controlled by replacing terminal phenylallylic groups with methyl groups or phloro-groups. Furthermore, a novel polythyramine polymer is synthesized with its principal chain constituted of NCH2CH2Si, the principal chain easy to disintegrate when exposed to an electron beam. The polymer is signal-responsive and may be patterned by use of an electron beam. As a temperature-responsive polymer with the hydrolytic feature controlled, poly(thyroxy ethylene glycol) is obtained from a derivative of diaminosiloxane and oligo-oxyethylene. This is a high-mobility, temperature-responsive material whose hydrolysis may be controlled. 3 refs., 2 figs.
